Value in percentage

Hello...i have a question here..how can i display the value in an olap report in percentage(%) based on the selected criteria?...because currently i just use the wizard to display the value in percentage which is at the field setting wizard,i choose % of column..but the value is not correct bcoz it didn't display the % based on the criteria but it display the % of the column...the following is the example of the problem i had.

i'm using analysis services and sql server 2000..in the example that i gave earlier, there's a measure called Amount..as far as i know, we can't insert 2 same measure in the data field area in the pivot table..so for ur info, i've created a calculated members called Amount2 to get the Amount value (which means now i've exactly 2 same data but with different name) and then insert it in the data field area...after that i used the field setting wizard to convert the value to become %...i'm i doing the right thing?
